fix(doctor): respect preferred_engine/engine.default when reporting default model (#204)

* fix(cloud-router): prevent local HF org models from being misrouted to OpenRouter

get_provider() previously routed any "/" model to OpenRouter, which caused
locally-served models (e.g. mlx-community/Qwen3.5-27B-4bit-DWQ) to be sent
to the cloud instead of localhost:8080.

Adds _LOCAL_HF_ORGS module-level allowlist covering mlx-community/,
bartowski/, unsloth/, and lmstudio-community/. Returns None early for
these before the openrouter "/" check.

* fix(doctor): respect preferred_engine/engine.default when reporting default model

_check_default_model() iterated engines in sorted alphabetical order,
causing engines like 'lemonade' to be reported as the host for the
default model even when 'mlx' was configured as preferred_engine and
engine.default. Now checks the configured engine first, then falls back
to alphabetical scan.
